When it comes to choosing new windows for your home or project, the decision often boils down to two popular materials: aluminium and timber. Both have their unique benefits, but cost is a major factor for many homeowners and trade clients in Sussex and the South East. We want to help you understand the financial side of this choice clearly and simply. Let’s explore the cost comparison of windows made from aluminium and timber, so you can make an informed decision that suits your budget and style.
Understanding the Cost Comparison of Windows
Before diving into specific numbers, it’s important to understand what influences the cost of windows. The price you pay depends on several factors:
Material quality: Premium aluminium or sustainably sourced timber can affect the price.
Window style and size: Larger or more complex designs cost more.
Installation: Labour costs vary depending on the material and complexity.
Energy efficiency: Windows with better insulation may have a higher upfront cost but save money long term.
Maintenance: Some materials require more upkeep, adding to lifetime costs.
With these in mind, let’s look at how aluminium and timber compare.

Aluminium Windows: What You Pay For
Aluminium windows are known for their sleek, modern look and durability. They are lightweight but strong, making them ideal for larger window panes and slim frames. Here’s what you can expect in terms of cost:
Initial price: Aluminium windows generally have a higher upfront cost than timber. This is due to the manufacturing process and the material’s strength.
Installation: Installation can be straightforward but may require specialist skills, especially for custom designs.
Maintenance: Aluminium requires minimal maintenance. It doesn’t warp, crack, or swell, which means fewer repairs and repainting over time.
Longevity: Aluminium windows can last 30 years or more, making them a long-term investment.
In terms of price, aluminium windows typically range from £400 plus per window, depending on size and style.
Timber Windows: The Traditional Choice
Timber windows offer a warm, traditional aesthetic that many homeowners love. They can be crafted from various types of wood, each with different price points and durability.
Initial price: Timber windows often start cheaper than aluminium, especially if you choose softwood options. However, high-quality hardwoods can be more expensive.
Installation: Timber windows are generally easier to install but may require more precise fitting to prevent drafts.
Maintenance: Timber needs regular upkeep, including painting or staining every few years to protect against weather damage.
Longevity: With proper care, timber windows can last 20-40 years, but neglect can shorten their lifespan.
Prices for timber windows usually range from £300 plus per window, depending on the wood type and finish.
Are Timber Windows Cheaper Than Aluminium?
This is a common question, and the answer isn’t always straightforward. Timber windows can be cheaper upfront, especially if you opt for softwood or standard designs. However, the ongoing maintenance costs can add up over time.
For example, if you need to repaint or reseal your timber windows every 3-5 years, this adds to the total cost of ownership. Aluminium windows, while more expensive initially, require less maintenance and often come with longer warranties.
If you’re looking for a budget-friendly option right now, timber might be the way to go. But if you want to save money and effort in the long run, aluminium could be more cost-effective.

Factors That Affect the Cost Beyond Material
When comparing aluminium vs timber windows cost, it’s important to consider other factors that influence the final price:
Energy Efficiency
Both aluminium and timber windows can be fitted with double or triple glazing. However, aluminium frames conduct heat more than timber, so they often require a thermal break to improve insulation. This can increase the cost but also improve energy savings.
Customisation and Style
Timber windows offer more flexibility in terms of shapes, finishes, and detailing. If you want a bespoke look, timber might be more suitable but also more expensive.
Environmental Impact
Timber is a renewable resource and can be more environmentally friendly if sourced sustainably. Aluminium production is energy-intensive, but aluminium frames are recyclable and long-lasting.
Local Availability and Labour Costs
In Sussex and the South East, availability of materials and skilled installers can affect prices. Aluminium installers might charge more due to specialised skills.
Making the Right Choice for Your Home or Project
Choosing between aluminium and timber windows is not just about cost. It’s about balancing your budget with your style preferences, maintenance willingness, and long-term goals.
If you want low maintenance and a modern look, aluminium windows are a strong choice.
If you prefer a classic appearance and don’t mind regular upkeep, timber windows can be very appealing.
Consider the energy efficiency and environmental impact of each option.
Always get multiple quotes and check the quality of materials and installation services.
Planning Your Window Investment Wisely
Investing in new windows is a significant decision. Here are some practical tips to help you manage costs effectively:
Set a clear budget before you start shopping.
Prioritise energy efficiency to save on heating bills.
Ask about warranties and aftercare services.
Think about the lifespan of the windows and factor in maintenance costs.
Choose a reputable installer with experience in your chosen material.
By planning carefully, you can enjoy beautiful, functional windows that enhance your property’s value and comfort.
We hope this cost comparison has given you a clearer picture of what to expect when choosing between aluminium and timber windows.
